Well i don't think the sense of a progressive spring changes anything. fix any end point, apply a force to the other, it will always compress for the same length.
And any way the shock should fit at full extension, it happens when riding.

I've contacted Nitron. I have to measure up the shock. Should be 344mm. If not they will solve it. So I have to strip down the whole bike again to get the shock out :-)

If you take the linkage bones off completely, the shock will still be in exactly the same position at full extension as it would be with them fitted. Full extension is limited by the internal bump stops built into the shock.

The only thing that would bring the shock spring closer to the rear of the engine at full extension is if the shock's free length was too long. Have they sent you the right length shock?

You, as usual, were right. Checked the free lenght of the shock, after contacting Nitron, and I measured 352mm. The shock should be 344mm according to Nitron. So I sent it back to them and they will solve the problem.

Nitron already sent the shock back after one week. And it fitted straight away now.
They solved this problem really well. Thumbs up for Nitron.

Glad to hear that Arjen!
